so, ill tell you the set up then the problem. So, i got an orion hcca 15.2 in a ported enclosure 40 inch wide 17 inch height 14 inch depth. and a Hifonics 2000w rms amp. The problemis that i cant seem to hit certain notes in music, for example, everyone knows the david gehetta song, "titanium" at the start of the song (first 16 seconds) is just intro, no bass, then up to 31 seconds, you got a kind high bass, then kicks in to hard bass. But, on my system you dont get any bass untill the 31 seconds, it wont play the higher bass note, it does it on alot of songs, its really annoying coz at certain points of songs/music it just sounds like i have no sub, iv tried adjusting seetings on amp and stereo, but no joy..... could it be the enclosure? too big?
